CHECK Loox.

Application med February 25, 1922. seriai No. 539,221.

To all-'whom it may concern: 'f l Be it known thatI, W'IILIAM J. CQNNELL,

'a citizen of the United States, residing at r'Ihese checks are attached to the cars at the loading point and are removedtherefrom at the tipple. A comparatively great number of contrivances have been employed for holding the check on the c ar 'when the latter isin transit, a number of which automatically eject the check atthe tipple.; Regardless of such check holding means, it has been found that in a number of instances the checks have been lost or fraudulently removed, so that the miner does not receive recompense for work actually done.

1' It is the object of the present invention to produce a means for locking a check on a mining car in a manner whereby the same positively cannot be removed as long as the car is loaded.

It is a further object to produce a check lock for mining cars in which the check is in the nature of a key that is inserted in the barrel of a lock which is attached to the car and when arranged in the barrel and turned with the barrel, means is operated to arrange the same either in contacting engagement with the load in the car or in contacting engagement with the frame for the running gear of the car to prevent the turning of the barrel, and consequently the removal of the key from the barrel as long as the load is in the car or the' car is in position to receive the load, and whereby the barrel and key can only be turned Vwhen the car is tilted to dumping position.

The foregoing, and Vother objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure l is a side elevation of a miners coal car illustrating the application of the improvement.v

Figure 2 is a sectionalview on the line 2--2 of Figure 1, on an enlarged scale.

Figure 3 is a sectional view substantially 'similar @Figure 2, but' Showingthe car in dumping position to permit ofthe removal v of the-key from the lock barrel.

,v Figure 4 is a sectional perspective view of*l the lock casing.

' Figu're is a similar y:viewof the barrel andthe head which'is attached thereto.

Figure 6 is a'view Figure 7 is a view illustrating the manlock is turned to key retaining'position when the body `ofthe car is in load receivingposition. U A mining car, of the usualy construction,

. of the key which prov 'vides a check. l

ner in which the barrel or tumblerof the is illustrated inthe drawings, and is jindi-` lcatedby the numeral l. Through one side o f the car, adjacent to lthe'bofttom thereof,

jacent to its outer end is providedwith an v Y inwardly directed annular flange 4. The bore of the casing 2, at a suitable distance away from the face plate 3 is provided with a substantially semi-cylindrical groovev 5, and with a longitudinal slot 6 that communicates with the groove and also passes through the face plate l. The turnable member or barrel of the lock is indicated by the numeral 7, Athe same having a reduced extension whereby the barrel proper is in contact with the shoulders provided on the inner face of the face plate and the annular rib on the inner end of the cas-V ing. The reduced extension of the barrel is indicated by the numeral 8 and extends through the casing. The extension 8 has on its end a laterally extending head 9.

The barrel 7 'from its outer end is provided with a longitudinal slot 10.

mal

The key, whichk also provides the check bit, when the key is passed .through the key' v hole opening in the face plate, casing and barrel being arranged in alignment With the semi-cylindrical groove in the casing so that when the key is turned and the barrel revolved the head 8 will be in a position to be contacted by the load in the car andl the Weight of such load Will prevent the accidental turning of the barrelvto Vrelease the key from the lock.

As soon as theload isdumped, it Will be apparent that the barrel can be turned to permit of the Ikey or check being removed kfrom the lock.

, tion, When taken in connection With the drawings Will fully set forth rthe simplicity of the construction and the advantages of the improvement to those skilled in the art to which suchinventions relate.

Having described the invention, I claim In combination with a dump car, of means for locking a check key thereto, comprising` a cylindrical casing received through one side of the car, an annular flange formed with the casing adjacent to its inner end, a face plate threadedly secured to its outer end, and having a notched opening registering with the bore of said casing but being of less area than that of said bore, a barrel received in the casing having an inner reduced end projecting through the inner end of the casing and being provided with a longitudinal slot designed to register with the notch when the barrel is in one position, a laterally extending head carried by the project-l ing end of the barrel, said .casing being provided With a semi-circular groove which communicates with a longitudinal slot entering from rthe outer end thereof and said slot being aligned With the notch in the face plate whereby a key may be inserted through the notch, the longitudinal slot of the casing andthe slot of the barrel respectively to turn the lateral extending head through the medium of the barrel to a position to be contacted by the load in the car, as and for the purpose specified.
